Forward Positioning

TM55-1730-228-13&P

(a) While approaching the aircraft, center SPEMS platform with the aircraft.

(b) Elevate SPEMS to approximately 11 feet (3.4 meters). The platform height may be adjusted approaching

the aircraft so platform will clear the fuselage.

CAUTION

It is critical that SPEMS be centered to the aircraft. The total clearance between the deck extension

opening and the aircraft is approximately two inches (5 cm). Failure to do so will result in extensive

aircraft damage.

NOTE

The top section of the deck extension guardrails cannot be removed or reinstalled to clear the rotor if the

platform is closer than four inches (10 cm) to aircraft.

(d) Slowly drive forward keeping SPEMS centered with the aircraft. Stop forward motion 8 to 12 inches (20 to

30 cm) from the aircraft.

(e) Traverse deck to four inches (10 cm) of aircraft forward crown.

(f) Lower stabilizers.

(g) Shutdown SPEMS.

CAUTION

Push deck extensions slowly. The height of SPEMS platform is critical. Take care to prevent grounding of

SPEMS extensions on the aircraft.

(h) Extend deck extensions.

(i) Attach static discharge lines.
